User Reviews

Users repeatedly praise the app for reliable wake-ups, sleep insights, and a free functional experience, plus soothing soundscapes and a simple interface. However, recurring issues include intrusive ads (often loud and hard to close), occasional alarm failures, pricing/subscription frustrations, clumsy ad UX, and weak customer support. The core value remains strong when alarms wake users and sleep tracking works, but monetization and reliability concerns drive most criticisms.

Pros

Reliable alarm that consistently helps wake users up.
Sleep tracking and health integration (Apple Health/Personify) with sleep insights.
Free version provides useful features and works well.
Calming sound options and sleep soundscapes (beach waves) for sleep ambience.
Simple dial interface with handy snooze features (easy to use).

Cons

Persistent, intrusive ads, including loud ads, that disrupt use and cannot be easily closed.
Alarm can fail to sound or stop working after updates, causing lateness.
Pricing changes and unclear premium features; frustration with subscriptions and features reverting to free with ads.
Ad UX and overall navigation are unintuitive (red X not removing ads; difficult UI).
Poor customer support or lack of help for paid features (slow responses, no contact).

I used to LOVE this alarm and used it for years. The last couple of years I’ve been a stay at home mom and have rarely needed an alarm. Now my son is in school full time and I’m back to needing an alarm every day. This app does NOT work like it used it, I’m so so so disappointed. First of all, if you listen to white noise and have it playing when the alarm goes off, it blasts the volume to 100% when the alarm is set to go off, which scares the hell out of me and wakes me up before the alarm even starts. Whatever, I figured I could start playing white noise on my TV instead. But now I’ve noticed that the volume doesn’t gradually increase anymore! It used to start nice and quiet and gradually get louder over a couple of minutes, which I loved because I absolutely hate the jarring sound of an alarm, even a pleasant sounding one. Now it’s just a regular loud alarm like every other one out there. It also doesn’t seem to wake you during the light part of your sleep cycle like it used to either, which was surprisingly very helpful even if it went off a few minutes earlier than you wanted it to. I’m so so so disappointed. I loved this alarm and it worked so well before.

I've been looking for an app that can wake me up a little less aggressively than my normal alarm, and I thought this might work with the 30 minute wakeup, but no. I often listen to white noise or an audiobook through headphones to fall asleep, but when this first alarm starts, it increases whatever other audio is playing to 100%, blasts my eardrums, and shocks me awake more aggressively than my regular alarm. I've tried turning on "air play" in the app and turning the volume for the alarm itself to 0, nothing works. App doesn't have support available beyond generic faqs so here we are.
